| 【目的】研究鲁北平原（黄河以北）土壤盐渍化现状。【方法】采用二级模糊综合评判法，构造了隶属土壤环境条件、地下水环境条件和自然地理条件3个层面，盐渍土面积占比、土壤盐渍程度、土壤含盐量、包气带岩性、地下水埋深、地下水矿化度、地形地貌与蒸降比8个指标的综合评价指标体系，对鲁北平原（黄河以北）区域进行了土壤盐渍化环境质量评价研究。【结果】①将鲁北平原（黄河以北）盐渍化土壤环境质量划分为优等、良好、中等、较差和差5个等级。②其中，盐渍化土壤环境质量差区面积5 277.49 km2，盐渍化土壤环境质量较差区面积6 564.76 km2，盐渍化土壤环境质量中等区面积4 383.79 km2，良好区面积5 995.52 km2，盐渍化土壤环境质量优等区面积4 919.29 km2。针对不同的盐渍化环境质量条件。将土壤盐渍化的防治分区划分为3个防治区8个亚区。【结论】鲁北平原（黄河以北）地区土壤盐渍化程度和空间差异较大。本研究可为改善该地区土壤管理措施提供技术支持，促进该地区农业和农村经济的健康发展。 |

| Abstract: |
| 【Objective】Soil salinity is a common abiotic stress most crops experience during their growth. Understanding its spatiotemporal variation and the underlying reasons is impetus to improve agricultural management. We propose a model in this paper to classify soil salinity and analyze the underlying mechanisms. The model is applied to the North of Yellow River in Northern Shandong Plain.【Method】The model is based on the two - level fuzzy comprehensive evaluation method. A comprehensive evaluation index system is constructed using soil environment factors, groundwater environmental factors, and physical geographical factors. It considered eight indexes: proportion of land areas affected by salinized soil, degree of soil salinity, soil salt content, lithology of unsaturated zone, depth of groundwater table, groundwater salinity, evaporation-prescription ratio, and topography and landform. The degree of soil quality was divided into excellent, good, moderate, poor, and very poor grades.【Result】 The areas of soil classified as very poor, poor, moderate, good and excellent based on soil salinization were 5 277.49 km2, 6 564.76 km2, 4 383.79 km2, 5 995.52 km2, and 4 919.29 km2, respectively. Based on their genesis and salinization, the salinized soils in the region can be divided to three areas consisting of eight sub-areas.【Conclusion】Soil salinity in the North of Yellow River in Northern Shandong Plain varies in its severity and space. The results presented in this paper can aid in improving soil management practices to promote a healthy agricultural and rural economy in the region. |
